MUAs that goof the semantics of the "Sender:" header field are either
not implementing EMail the way it has been specified by the IETF,
or they goofed the second part of the above explanation for SHOULD.
I wouldn't disagree. If you can find an Internet where everyone
correctly implements every RFC, I'd sure like to see it. In the
meantime, we're stuck with the one we have.
